Question 173083
48,000(1-.28)=48,000*.72=$34,560 is her balance after taxes.
.0325x+.0175(34,560-x)=904.80
.0325x+604.80-.0175x=904.80
.015x=904.8-604.8
.015x=300
x=300/.015
x=$20,000 is the amount invested @ 3.25%
34,560-20,000=$14,560 is the amount invested @ 1.75%
Proof:
.0325*20,000+.0175*14,560=904.80
650+254.80=904.80
904.8=904.8
